We removed the exception handling for Rugged errors in !16770, which
revealed that the licensee gem attempts to retrieve a license file
via Rugged in `refs/heads/master` by default. If that branch
did not exist, a Rugged::ReferenceError would be thrown.

There were two issues:

1. Not every project uses `master` as the default branch. This
change uses the head commit to identify the license.

2. Removing the exception handling caused repositories to fail
loading. We can safely catch and ignore any Rugged error because
this means we weren't able to load a license file.

Closes #43268
